RAYMONDLD. TAYLOR,1OF EVANSTON, ILLINOIS, ASSIGNOR T0 UNITED-CABRFASTENER CORPORATION, 'OF'-.'CAMBRIDGE, MASSACHUSETTS, A CORPORATION OFMASSACHU SETTS LOCKING smmm 7 Application. filed March 22, 1932 SerialNo. 600,417.

My invention aims toprovide improvements in multiple fastener-slidersand lock ing means for the same.

In the drawing which illustrates a preferred embodiment of my inventionFigure 1 is a plan view of a portion of a multiple fastener installationshowing my improved slider locking means in locking position, thepadlock being shown in dotted lines to prevent parts being obscured;

Fig. 2 is an enlargedsection taken on the line 2-2 of Figure 1; and

Figs-3 is a side elevation of the installation shown in Figure 1, thepadlock being removed and the pull. tab being shown in position foroperation of the slider.

While I am aware ofthe fact that padlocks have been used in variouswaysand combinations, with sliders of the class illustrated, for lockingpurposes, I believe that my combination of elements provides a simpleeflicient unit which is far superior to any heretofore disclosed. Infact, my strucprovide a slider con struction which can be locked whendesired without cooperation with any other part or parts affixed to theinstallation and it is positive in operation because it has lockingmeans positively'engaging the multiple fasteners and other means forholding the looking means in such position. Furthermore, theconstruction of the slider and associated parts is simple and involves aminimum of parts.

Referring now to the specific embodiment of my invention selected forillustration, there is shown (Figure 1) portions of a pair of stringers1 and 2 at the adjacent edges of which are the usual interengagingfastener elements 3. The slider device includes the usual channel member4 for engaging and disengaging the fasteners 3.

The means for locking the slider in position to prevent operationcomprises fastener-engaging locking means 5 carried by a pull tab faceof the slider, and a padlock 8, all shown in Figs. 1 and 2.,

The rib-like part 7 is. a thin plate attached edgewise to the front faceof they 6, a rib-like'part 7, at the front channel member 4 andextending the length thereof. Itis held in fixed position by anattaching element 9 at one end and an attaching element .10 at the otherend. The

latter extends through an upstanding lip 11 at the lower edge of thechannel, as best shownin Fig. 2. Av notch 12 is cut in the part 7 andthe pull tab 6 is pivoted therein.

A slot 13 is provided in the pull tab to permit swinging movementthereof relative to the part 7. An aperture 14 is provided through thepart 7 at a point which is spaced about the thickness of the pull tab 6from the front face of the channel member 4.

\Vhile one fastener-engaging member 5 Y may be used to provide thelocking means, I prefer to use two, one at each side of the part 7adjacent the pivot point of the pull tab. These fastener-engagingmembers 5 (Figure 1) pass through apertures 15-15 in the channel 4 sothat they may engage be tween the fastener members 3 on each of thestringers 1 and 2.

When it is desired to lock the slider so that the fastener members 3cannot be separated the pull tab is pressed into the position shown inFigs. 1 and 2 where the members 5-5 engage between the fastener members3. Then the padlock 8 or other suitable-device is inserted through thehole 14 in the part 7 to hold the tab in locked' position. Upon removalof *the padlock 8 the pull tab may be swung to a position as shown inFig. 3, thereby removing the members 5-5 from between the fastenerelements 3. The slider then may be moved longitudinally relative to thefastener elements and stringers.

My device is particularly desirable on devices which require locking,because it is simple and positive in operation and the installation isexactly the same as other multiple operative fastener installationswhere no locking is required.

While I have illustrated and described a preferred embodiment of myinvention, I do not wish to be limited. thereby, because the scope of myinvention is best defined by the following claim- I claim:

A locking slider structure comprising, in combination, a channel devicefor engaging and disengaging opposed series of fastener elements adaptedto pass therethrough, a pull tab attached to the channel device,fastener element engaging locking means as-' sembled as a part of theslider structure and operable "by the pull tab to locktheslider againstmovement relative to a the;

fastener elements when the pull tab is in a predetermined position, aone-piece riblike part substantially free of lateral r0- jectionsrigidly secured-to and exten ing substantially the entire length of thechan-V nel device and extending away from one channel thickness ofthepull tab and a locking member passing through said apertureand holdingsaid pull tab securely against the face of the channel, thereby to holdthe locking means and the pull tab in slider locking position.
